Remarkable discoveries and advances in two-dimensional semiconductors beyond graphene, designer meta-surfaces, and integrated quantum or non-linear photonic devices are driving a revolution in optoelectronic and photonic technologies. The Two-Dimensional Photonics Fabrication Facility at Heriot-Watt University will facilitate this revolution in the UK with a user facility unique to the UK landscape. The centrepiece instrument, a "maskless" direct write laser, is a lithographic tool to rapidly fabricate large scale but bespoke 2D photonic devices with novel functionalities. The maskless laser writer bridges the gap in lateral resolution and write speed between electron beam lithography and conventional photolithography to enable rapid fabrication of nanoscale photonic devices over large areas. The unique lithography system will be augmented by an electron beam evaporator enabling deposition of high-quality metals and dielectrics with nanometre precision onto devices lithographically defined by the direct write laser. Finally, for the ultimate in thin-film, surface and materials metrology, a spectroscopic imaging ellipsometer will be used. This unique instrument is crucial for characterization, either pre- or post-fabrication by the lithographic tool, of emerging two-dimensional semiconductor devices. The facility will be integrated into the newly refurbished cleanroom at Heriot-Watt University housing an array of complementary equipment. This will underpin emerging 2D photonics research for numerous PhD students and early career and established academics at HWU and across the UK. The facility strongly leverages existing excellence in photonics research within the Institute of Photonics and Quantum Sciences at Heriot-Watt and a large cohort of prospective facility users exist within two EPSRC centres for doctoral training, two UK Quantum Technology Hubs, and the EPSRC Centre for Innovative Manufacturing in Laser Based Production Processes. Four specific research thrusts will be enabled by the facility:1. Two-dimensional quantum photonics based on recently discovered quantum emitters embedded in 2D semiconductors 'beyond graphene' that can produce a remarkably wide range of electronic and optical properties. Novel devices will be fabricated to drive forward this exciting emergent quantum photonic platform.2. Ultrathin optical devices made from metasurfaces, which are two-dimensional metamaterials exhibiting unusual optical properties. The facility will enable rapid fabrication of large-scale metasurfaces to create 'flat' optics for potential applications (e.g. microscopes, cameras, displays, and mobile phones) across a range of frequencies (e.g. visible - terahertz). 3. Fabrication of integrated photonics devices including optimized single photon focal plane arrays, microlens arrays, mosaic filters, low-loss waveguides, and high-quality cavities for quantum, non-linear, and ultra-fast photonics. 4. High-resolution characterization for a wide-range of novel thin film and two-dimensional semiconductor materials and devices.

石墨烯之外的二维半导体，设计器元表面表面以及集成的量子或非线性光子设备的杰出发现和进步正在推动光电和光子技术的革命。 Heriot-Watt University的二维光子制造设施将促进英国的这一革命，其用户设施是英国景观所特有的。核心仪器是一种“无掩模”直接写激光器，是一种迅速制造大型但定制的具有新功能的2D光子设备的光刻工具。无掩模的激光作者在横向分辨率上桥接了缝隙，并在电子束光刻和常规光刻之间编写速度，以便在大面积上快速制造纳米级光子设备。独特的光刻系统将通过电子束蒸发器增强，从而使高质量金属的沉积和纳米精度的高质量沉积到直接写激光器定义的设备上。最后，对于薄膜，表面和材料计量学的最终，将使用光谱成像椭圆计。这种独特的仪器对于出现的二维半导体设备的光刻工具（通过光刻工具）进行表征至关重要。该设施将集成到Heriot-Watt University新近翻新的洁净室中，设有一系列补充设备。这将为众多博士生和早期职业的新兴2D光子学研究提供支持，并在HWU和整个英国建立了学者。该设施强烈利用Heriot-Watt的光子学和量子科学研究所的光子学研究中的现有卓越，并且在两个EPSRC中心内存在大量的潜在设施使用者，用于博士培训，两个英国量子技术枢纽和EPSRC Innovative Innovative Innovative Innovative Innovative Innovative Innovative Innovative Innovative Innovative Innovative Innovation Innovation Innovation Intoverative Innovation Intovative Innovation Intovation Innovation Intervorative in Laser基于Laser的生产过程。该设施将启用四个特定的研究推力：1。基于最近发现的量子发射器的二维量子光子学嵌入了2D半导体中的“超越石墨烯”中，它们可以产生相当广泛的电子和光学特性。新颖的设备将被制造出来，以推动这个令人兴奋的新兴量子光子平台2。超薄光学设备由元整日制成，它们是二维超材料，表现出异常的光学特性。该设施将使大规模跨国空间快速制造，从而为潜在的应用（例如显微镜，相机，显示器和手机）创建“平坦”光学器件（例如，可见的 - Terahertz）。 3。集成光子设备的制造，包括优化的单光子焦平面阵列，Microlens阵列，镶嵌过滤器，低损耗波导和用于量子，非线性和超快速光子学的高质量腔。 4。大量新型薄膜和二维半导体材料和设备的高分辨率表征。
